Walmart Marketplace is not a sign-up form you fill in and forget. It's an application, and Walmart reviews it like one: your business records, your track record as a seller, and your plan for getting orders to customers and taking returns back. Prepare all three before you start, and the process is mostly clerical. Start cold, and you'll be hunting for documents mid-application.
If you're researching how to register as a Walmart Marketplace seller, the work breaks into three tasks:
Check the Walmart Marketplace seller registration requirements against your current business.
Gather the documents needed to sell on Walmart Marketplace.
Confirm your products and fulfillment arrangement are ready for review.
This guide covers the U.S. marketplace. The exact documents Walmart requests depend on your country of incorporation and business type, so treat the checklist inside your own application as final.
What Documents Do I Need to Register as a Seller on Walmart Marketplace?
Start with the list Walmart itself publishes. You'll need:
A business tax ID or business license number. Walmart is explicit that a Social Security number is not accepted in place of the business identifier.
Supporting documents that verify your business name and address — registration records, and proof of address if it's requested.
A personal, government-issued ID for the applicant or legal representative applying on the business's behalf.
A selling track record. Walmart asks for a history of marketplace or ecommerce success, so have links to your existing stores and accurate figures for your selling history ready to share.
Products with proper identifiers. Walmart expects GTIN/UPC numbers backed by a GS1 Company Prefix. If a product genuinely has no product ID — some private-label and handmade items don't — Walmart lets you request a GTIN exemption instead, but sort that out before you build the catalog.
A fulfillment arrangement. Either Walmart Fulfillment Services (WFS) or your own B2C U.S. warehouse setup, in both cases with the ability to handle returns.
Build a preparation folder with clearly labeled sections:
Business identity: legal name, entity type, registration or license number, business phone number.
Applicant identity: the ID and contact details of the person applying.
Supporting documents: business registration records and any requested evidence of address.
Sales experience: links to your existing stores and your selling history.
Product and fulfillment details: product identifiers (GTIN/UPC), warehouse arrangements, and your returns process.
Keep the records you gathered proactively separate from the documents Walmart specifically asks you to upload. When the application requests something, you'll know in seconds whether you already have it.
How Do I Sign Up and Register as a Walmart Marketplace Seller Step by Step?
Walmart's onboarding runs: create your seller login, verify your business, configure payments and market details, arrange fulfillment, and set up your catalog. Those are the main steps to become a Walmart Marketplace seller:
Create the account. Use a business email address you'll actually monitor throughout the application.
Complete business verification. Enter the legal details exactly as they appear on your records and upload what's requested.
Choose a payout method. Payout providers vary by country of incorporation; connect the one that applies to you.
Add market details. Your business display name and customer service contact information.
Configure fulfillment. Shipping and returns arrangements you can support consistently, not just on a good week.
Set up the catalog. Accurate listings, product identifiers, and realistic quantities.
If you're learning how to set up a Walmart Marketplace seller account with a colleague, split the work: one person gathers records while the other checks product data and warehouse arrangements. Review everything together before anyone hits submit — mismatches between the two halves are what stall applications.
Check Your Walmart Seller Account Verification Documents
For Walmart business verification, documents must be in PNG, JPG, or PDF format, each file under 5 MB. Photo ID means the front and back, clear and legible. Open every file and read it yourself before uploading; a blurry registration certificate costs you a review cycle, and while verification can be as fast as a few minutes, it can also run to two business days — don't spend them on avoidable resubmissions.
Check names and addresses character by character. Say your registration certificate reads "Maple Ridge Retail LLC" while your storefront is "Maple Ridge Home." Keep both names clearly labeled in your folder, and use the legal name wherever Walmart asks for it. Do the same with numbers: your state registration number and your tax ID are different identifiers serving different purposes. Copy each one from its source document rather than typing from memory, and keep them in separate fields on your preparation sheet.
One deadline to respect: if Walmart asks for additional identity verification — which can involve photo ID plus facial recognition through a secure third-party service — you have seven days from the notification to complete it, or Walmart closes the account. Check Seller Center and your application email regularly while your application is live.
What Are the Requirements and Documents Needed to Create a Walmart Marketplace Seller Account?
The Walmart Marketplace seller registration requirements cover four areas — your business, the applicant, the catalog, and fulfillment — and the documents needed to sell on Walmart Marketplace are the evidence for each. Expect additional records if your business is incorporated outside the U.S.
Knowing how to register as a Walmart Marketplace seller is only half the preparation; the other half is being ready for the review behind it. For each product you plan to launch with, you should be able to answer three questions without pausing: who ships it, from where, and who receives it if it comes back. Check each product against Walmart's Prohibited Products Policy before it goes on your launch list, not after a listing is pulled.
Plan your cash flow before launch, too. New sellers are placed on a payment hold while they build sales history, and the length of the hold varies by country of incorporation. Budget enough to keep paying suppliers while your first proceeds sit in that hold.
Prepare Walmart Marketplace Fulfillment Before Listing
For dropshipping, walk a sample order through with your supplier before you list anything. Record the cutoff time, the processing estimate, the shipping service, how tracking reaches you, and the return address. Then compare those answers against the delivery promises you're considering putting on the listing.
A supplier's processing estimate is only one leg of the journey. Add carrier transit time and non-working days before you settle on the arrival date you'll show customers. And ask, in advance, how the supplier reports stock changes and what happens when an item sells out — because on Walmart, as on any marketplace, the supplier's stockout becomes your cancelled order.
When choosing suppliers for Walmart dropshipping, check their warehouse and fulfillment arrangements against your delivery plans, product by product.
Once your account is approved, connect your Walmart Marketplace account to Doba and check the syncing options for your store. Test a small set of listings and verify the information in both systems before you expand the catalog.
